Description
Technical field
The present invention relates to high temperature alloy preparation fields, and in particular to a kind of reduction high temperature alloy melt and oxide ceramics earthenware
The method of wetability between crucible.
Background technique
High temperature alloy has excellent antioxygenic property, corrosion resistance and higher elevated temperature strength.It is by widely
Turbo blade or other high-temperature components are protected as thermal barrier coating covering or bonding coat.In recent years, frequently with high temperature close
Golden method of smelting is vacuum induction melting (VIM), vacuum arc melting (VAR), electroslag remelting (ESR), vacuum induction power-up
Shu Chongrong (EBCHR), electron beam remelting (EBR) or in which two or three of combination, wherein vacuum induction melting is using the most
Extensively.During entire alloy smelting, when the crucible of liquid metal and 1000 DEG C or more contacts, due to the high activity of alloy
With the superhigh temperature in preparation process, lead to alloy melt and crucible reaction, the micro impurity element (O, N, S) in alloy melt increases
It is more, reduce the synthesis service performance of alloy.Wetability between crucible material and alloy melt is for understanding crucible and alloy
Between interfacial reaction mechanism and ceramic structure and interfacial reaction between relationship it is particularly important.If alloy melt is well
Crucible internal walls are soaked, then alloy melt will be permeated by the capillary on inner surface of crucible to ceramic surface, in crucible
Hazardous trace elements (for example, O, C, N) have the tendency that in fusion process into alloy melt, and lead to the bad of mechanical property
Change.In addition, the interfacial reaction between alloy melt and ceramic material is tended to occur under the conditions of good wetability.This is on boundary
New compound is generated at face and declines alloy metallurgy quality.Wetability can be characterized by the degree of wetting, apparently
It is upper that we are generally indicated with contact angle θ.Capillary force and interfacial reaction of the surface of solids etc. all can generate shadow to wetting speed
It rings.If θ=180o defines the completely nonwetting solid of liquid if us；The liquid complete wetting solid if θ=0o；Other situations
Such as θ > 90o, then it is referred to as nonwetting；θ < 90o is also known as soaked.Therefore, high temperature alloy melt and oxide ceramics earthenware are reduced
Wetability between crucible, and then regulate and control the chemical reaction of its interface, to the surface quality for improving high-temperature alloy casting, improve its mechanics
Performance is of great significance.
